Q: Can the USB adapter be connected to Gaming Controllers such as PS/XBOX?

A: It only supports connected PS4, X BOX ONE S and later series Gaming Controllers. Bluetooth devices all have latency issues（Latency 250ms）, If you need to connect game controller devices and have requirements for latency,

We recommend that you use a wired connection or a dedicated 2.4g adapter to achieve ultra-low latency and stability .
